To aZZ whom, t may concern.-

c c', into which the projections d d fit.

Beit known that we, FREDERICK G. SAR- GEN'r and ALLAN C. SARGENT, of Graniteville, in the county of Middlesex and State of Massachusetts, have :invented a new and useful Improvement in Squeeze-Rolls for Squeezing and Drying Fiber, of which Jche following is a specication., 'n

Our invention relates to squeezing and compressing rolls for squeezing and drying wool and other brous materials after being washed or soaked; and it consists in a novel attachment to produce the Compression ci'such rolls, substantially as hereinafter described.

In the drawings, Figure l is a side View of a squeeze-roll frameI and rolls provided with our invention. Fig. 2 is a section through line m g/.of Fig. l. Y

A is the frame of the machine.

B B are the squeeze-rolls.

C is a feed-apron by which the ber is carried to the rolls.

a c are the rollers which carry the feed apron.

c c is a pair of levers pivoted at Z) and rest- `ing on the upper side of the boxes of the upper squeezeroll. On the upper sidesA of these levers, near their outer, ends, are a series of projections, cZ CZ, being opposite to each other when the levers are in place in the machine.

a is a bar, of metal or other suitable material, having in its lower side two depressions, By the construction and arrangement of this bar a', as'described, a superior and equalizing action of theweights g g upon the upper roll, B, i-s secured, as well as a much cheaper and more durable construction of the several parts. This equalization of the weights upon the upper roll, B, is produced by the bearing-point of the bar a upon each lever c being placed between the points on said bar when the weights exert their pressure upon said bar near each end by means of the levers Z Z and connecting-rods c, e. It is obvious that with this construction a proportional part of the pressure of each weight will be exerted upon the same lever c, and thus tend to equalize the pressure upon both ends of the roll B,

which is important when the wool passes 11nder the roll in greater quantities or masses near one end than near the other, as is frequently the case in practice. AIn-order to facilitate this action of the combined parts thev conoidal-pointed nuts b and their corresponding sockets in the bar c are used as well as the notches c c and corresponding beveled edges of the levers c c, passing through them.

which nuts, connected with the hand-wheels b b', are tted, these nuts being egg-shaped at their lower ends where they come against the bar c'. The shape of these nuts allows the .freeunovement of the rods e e in the bar c as it works up and down. e is a spiral spring resting on the bar a, and serving to assist in compressing the rolls.

At their lower ends the rods e e are provided' with stirrups m mf, surrounding the levers g y. The stirrups iit into notches Z Z in the lower sides of the levers, and by moving them from one notch to the other a greaterV or less com pression is produced, as desired. By combining the shifting of the bar a upon the different pairs of projections cZ CZ, with this shifting of the stirrups in the notches Z Z any desired degree of compression can be produced.

rllhe levers g gare pivoted to the frame at n, and have weights hung on their outer ends, as shown.

rlhe squeeze-rolls may be used separately, as shown, or may be applied to a wool-washing or other similar machine in which it is desired to squeeze or compress the ber.

HVhat we claim as new and of our invention, is# ,Y 1. In combination with the squeeze-rolls B and levers c c, the bar a', rods c c, and levers nuts b, rods ff, and levers g, substantially as g, substantially as described. described.
